Discriminative Phrase Selection for Statistical Machine Translation
Posted on 2011-06-25 12:44:15
Traditional statistical machine translation (SMT) architectures, like the one implemented in this chapter, address the translation task as a search problem (Brown et al., 1990). Given an input string in the source language, the goal is to find the output string in the target language which maximizes the product of a series of probability models over...
Reranking for Large-Scale Statistical Machine Translation
Posted on 2011-06-19 07:14:05
Statistical machine translation systems conduct a nonexhaustive search of the (extremely large) space of all possible translations by keeping a list of the current n-best candidates. In practice, it was observed that the ranking of the candidates within the n-best list can be fairly poor, which means that the system is unable to return the best of...
Proper Names and Machine Translation
Posted on 2011-06-17 09:42:02
Starting from the observation that “name translation has proven to be a challenge for machine translation providers,” Hirschman et al. (2000) identified the following three types of problems related to proper names: 1. Translation of proper names as if they were normal meaningful words (e.g., the name of the former German Chancellor Helmut Kohl...
Automatic Evaluation Metrics

Automatic Evaluation Metrics Levenshtein-Based Measures A first group of measures is inherited from speech recognition and is based on computing the edit distance between the candidate translation and the reference. This distance can be computed using simple dynamic programming algorithms. Word error rate (WER) (Niesen et al., 2000) is the sum of insertions,...
Evaluation of Machine Translation
Posted on 2011-06-13 09:41:52
Evaluation of Machine Translation Entire books have been devoted to discussing what makes a translation a good translation. Relevant factors range from whether translation should convey emotion as well and above meaning, to more down-to-earth questions like the intended use of the translation itself. Restricting our attention to machine translation,...
Machine Translation Background
Posted on 2011-06-12 12:33:14
Machine Translation Background Machine translation (MT) has a long history of ambitious goals and unfulfilled promises. Early work in automatic, or “mechanical” translation, as it was known at the time, goes back at least to the 1940s. Its progress has, in many ways, followed and been fueled by advances in computer science and artificial intelligence,...
New EU Language Regulations For Pharmaceutical And Medical Device Manufactures
Posted on 2009-10-16 04:29:54
Latest EU regulations demand that all packaging and instruction leaflets for pharmaceutical products and medical devices are translated into the official language of the country they are being exported to.
